Subject external table file lock
Author RB Smissaert
Have come across a problem in Interbase 5.6 and that is that
the files associated with external tables (in this case text files)
can't be deleted without stopping the Interbase server. This is even after
dropping the table. Stopping the server is no option, so it looks I am stuck
Has this been fixed in Firebird 1.5 or 2.x?
